Teaching Mathematics Using History and Fairy Tales Daryl Stephens and Robert Davidson Department of Mathematical Sciences East Tennessee State University Tennessee Association for Developmental Education 20 th Annual Conference October 28, 2003 – Memphis, Tennessee
Why integrate history and stories into math class? n n n To humanize mathematics Connect real-life experiences with mathematics Show people in the real world use math Relax students and alleviate math anxiety Solve problems Illustrate concepts by stories

Thomas Hariot (1560 -1621) n n n Introduced < and > as we use them today First to write exponents as we do (a 3 instead of aaa) Helped Sir Walter Raleigh map NC Discovered sunspots Died of cancer from tobacco
William Oughtred (1574 -1660) n n Introduced the × for multiplication Introduced : : for proportion and ~ for difference between Clergyman who gave free math lessons Famous pupils: John Wallis, Christopher Wren, Seth Ward
Gottfried Wilhelm von Leibniz (1646 -1716) n n Used both • and for multiplication Calculating machine (first mechanical to multiply and divide) Developed binary numeral system Co-creator of calculus
Johann Heinrich Rann (1622 -1676) n Introduced the ÷ symbol for division (although this symbol was used by many continental Europeans for subtraction).
Christian Kramp (1760 -1826) n n First to use the n! symbol for factorials in 1808 Used because of printing problems with a previously-used symbol
Evariste Galois (1811 - 1832) n n “Unfortunately what is little recognized is that the most worthwhile scientific books are those in which the author clearly indicates what he does not know; for an author most hurts his readers by concealing difficulties. ” Died in a duel over a woman’s love
Connecting Real-life Experiences
Real World Examples n n n Reading blueprints Packing furniture “Inequalities will never affect me!” Emily’s inequalities Calculator project Cartesian inequalities and the tennis court
Relax students and help alleviate math anxiety
Math wasn’t created to make students miserable, but to solve problems! n Religion Pyramids n Astronomy n n Politics n n Sputnik Money n Geometry and Egyptian taxation
Illustrate a point with a story
The Key Story n n n Try turning it upside down! Factor: 21 x 2 – x – 10 (3 x + 5)(7 x – 2) doesn’t work Try switching around to (3 x + 2)(7 x – 5)
Dr. Seuss’s The Sneetches n n n Functions Composite functions Inverse functions
The Cat in the Box Dana Michel, Wonder Books, 1963 n Subsets n Sets of numbers
Trolls and Negative Exponents n Working with rational expressions with negative exponents such as:
“The Elephant and the Squirrel” n n Children’s story by Bill Sprague from A Treasury of Bedtime Stories (ed. Judith Klugmann, Doubleday, 1960). Stop and look at other ways of solving problems besides the obvious!
Your Turn Any stories you’d like to share?
